Travel hacking is the art of using various strategies to save money on travel expenses, particularly flights and accommodations. By taking advantage of credit card rewards, loyalty programs, and special promotions, travelers can earn points or miles that can be redeemed for free or discounted trips. This allows them to explore new destinations without breaking the bank. Many travel hackers also utilize tools like flight comparison websites and travel blogs to find the best deals and tips. By staying informed about the latest offers and learning how to maximize their rewards, they can enjoy more adventures while spending less money.
